PUZZLE.

Specification of Letters Patent.

Patented Oct. 11, 1921.

Application filed October 21, 1920. Serial No. 418,348.

To all whom it may concern:

Be it known that I, GEORGE A. PARMENTER, a citizen of the United States, and a resident of West Medford, Massachusetts, have invented certain new and useful Improvements in Puzzles, of which the following is a specification.

This invention relates to puzzles and aims to produce an interesting, amusing and apparently impossible problem to solve.

Another object is to produce a'puzzle of compact form and simplicity of structure which may be readily and cheaply manufactured without complicated and expensive machinery.

The invention comprises four links of wire all of the same length bent into two distinct shapes and with a ring fitted thereon. The shape of the links is such that the width of the end links is greater than the diameter of the ring and therefore presents an ap parent impossibility to remove the ring from the links.

In the drawing which shows one manner in which the invention may be carried out- Figure lis an extended view of the puzzle.

Fig. 2 is a view showing how the problem may be solved and the path of the ring being shown in dotted lines.

The puzzle consists of two pieces of wire 1 and 2 the ends of each being provided with eyelets 3 and joined thereby. As shown the two links 1 and 2 form a substantially rectangular link hinged at its center. At tached to links 1 and 2, also by means of eyelets 3 are substantially triangularly shaped links at and 5 having their eyeleted ends open to a slight extent. It is to be noted that any side of links a and 5 is longer than the diameter of the ring 6.

To remove the ring it is slipped onto link 4 which is made to assume a position on the long'side of link 2 adjacent one set of eye lets joining links 1 and 2. Link 5 is now slid down along link 1 until the base of the triangle abuts the short side of the rectangle.

pon folding link 1 upon link 2 it will be found that the ring may be made to travel around one set of eyelets joining links 1 and 2, inside links 1, 2 and 4 and off the assembly.

It is to be noted that each link is bent from equal lengths of wire, and each has similar eyelets. This tends to cheapness of manufacture, a very serious problem in the success of a commercial article of this type.

It will now be apparent that I have devised a puzzle, simple and cheap to construct and though presenting an apparently impossible problem, may be readily solved.

What I claim is A puzzle comprising four links of equal ultimate length, the two central links having straight elongated side portions, a short end portion, the ends of the side portions of each link being joined to each other to form straight lines from end portion to end portion, and a ring surrounding one of said links.

In testimony whereof, I affix my signature.

GEORGE A. PARMENTER.
